| File extension | .MP3 |

| Description | MP3 is the most popular audio file type based on MPEG-1 Layer III compression. Its lossy algorithm was developed in 1991. MP3 codes the sound almost with the same quality, as CD (16-bit stereo), providing compression in size 1 to 10 from the original WAF or AIFF tracks. The quality of MP3 seriously depends on the bitrate. It can be 128 - 256 kbps. Higher bitrates are also supported, but they seriously increase the file size. It is supported by all modern hard- and software players. |

| Description | MP4 files can contain video and sound data. It is a file container that supports different multimedia content types such as multiple audio streams, subtitles, 2D and 3D image frames. MP4 is also used for streaming media services (online or digital TV). This file type supports the control of transmission speeds for media signal, as well as correcting corrupted frames. Thanks to comparatively low system requirements, MP4 is now the most popular container type for sharing media. |

Most social media platforms — YouTube, Instagram, Facebook, and TikTok — accept video files but not standalone audio. Converting an MP3 to MP4 wraps the audio stream inside a video container without changing the sound quality. The result is an MP4 file that uploads to any platform, plays in any browser, and satisfies format requirements that block raw MP3 files. Drop your .mp3 and download a ready-to-upload MP4 in seconds.
MP3 is a pure audio format — it stores compressed audio data with no video track. MP4 is a container format that can hold audio, video, subtitles, and metadata in a single file. When you convert MP3 to MP4, the audio stream is placed inside an MP4 container with a minimal or blank video track — the audio itself is not re-encoded, so no quality is lost. The result plays audio through any video player, media software, or web browser that accepts MP4.
